DANGER
Shortness of breath and poisoning caused by inhaling phosgene gas
When welding workpieces that have been degreased with chlorinated solvents, phosgene
gas is formed.
• Do not inhale smoke and vapours.
• Ensure a sufficient supply of fresh air.
• Rinse the workpieces with clean water prior to welding.
• Do not place degreasing baths containing chlorine in the vicinity of the welding area.
DANGER
Risk of burns
During welding activities, sparks, glowing workpieces or hot slag can produce flames.
• Check the work area for flashpoints.
• Provide appropriate fire extinguishing equipment in the workplace.
• Allow workpieces to cool down after welding.
• Prior to performing welding work, properly fasten the ground clamp to the workpiece or
welding table.
